This is a copy of an issue originally filed as gdb bug at
http://sourceware.org/bugzilla/show_bug.cgi?id=11639 that was identified as a
gcc issue in the mean time:
If 'Derived' and 'Base' are setup as shown in the attachment
void Derived::foo()
{
Base *b = this;
Base &br = *b;
}
then
'print b'
yields "$1 = (void *) 0xbfffee38", i.e. the type information for 'b' is
completely lost.
It should print (Base *) 0xbfffee38.
The problem is not present in g++ 4.4.
